Abstract
L'invention concerne un procédé et un système de surveillance de température corporelle centrale non invasifs et sans contact, comprenant une caméra infrarouge, un processeur et un support lisible par ordinateur non transitoire présentant un programme pour analyser des images thermiques de l'œil humain. L'invention concerne également le procédé d'utilisation du système, comprenant l'isolement d'images thermiques oculaires à partir d'une image faciale ; l'extraction d'informations thermiques concernant la surface de l'œil ; la transition des informations thermiques à un modèle sélectionné de l'œil ; l'estimation d'une température à l'arrière de l'œil ; l'optimisation de la température estimée à l'arrière de l'œil et la transmission des informations de température optimisée à un dispositif de sortie.
